Abstract

La présente invention vise un procédé de détermination de l’amplitude d’un mouvement effectué par un membre d’un corps articulé. Ledit procédé comprend : une obtention (E12) d’un segment représentatif du positionnement du membre dans un référentiel donné à l’issue dudit mouvement, une génération (E16) d’un modèle du membre en trois dimensions, positionné dans ledit référentiel à l’aide du segment obtenu, une obtention (E14) d’un nuage de points en trois dimensions représentant le membre dans ledit référentiel à l’issue dudit mouvement, à partir d’une information de profondeur fournie par un capteur, ladite information de profondeur définissant une scène en trois dimensions comprenant au moins une partie du corps articulé incluant ledit membre, un repositionnement (E17) du modèle du membre de façon à minimiser un critère d’erreur prédéterminé entre le nuage de points obtenu et ledit modèle, et une détermination (E18) de l’amplitude du mouvement, à partir du nouveau positionnement du modèle du membre. Figure pour l’abrégé : figure 2The present invention relates to a method for determining the amplitude of a movement performed by a member of an articulated body. Said method comprises: obtaining (E12) a segment representative of the positioning of the member in a given frame of reference at the end of said movement, generation (E16) of a model of the member in three dimensions, positioned in said frame of reference at the using the segment obtained, obtaining (E14) a cloud of three-dimensional points representing the member in said frame of reference at the end of said movement, from depth information supplied by a sensor, said depth information defining a three-dimensional scene comprising at least a part of the articulated body including said limb, a repositioning (E17) of the model of the limb so as to minimize a predetermined error criterion between the cloud of points obtained and said model, and a determination (E18) range of motion, from the new limb model positioning.
